Choose da when two noun phrases fill one grammatical slot: ruwa da madara “water and milk,” Aisha da Musa “Aisha and Musa.” Choose kuma when you add a second proposition, a further event, or another participant’s contribution: Aisha ta kawo ruwa, Musa kuma ya kawo madara “Aisha brought water, and Musa brought milk.” English and covers both jobs, but Hausa grammar keeps them distinct.
All unlabelled examples are (neutral Nigerian Standard Hausa). Da also means “with,” so a postverbal sequence can express accompaniment and may even be genuinely ambiguous. Kuma is additive; it does not inherently mean “then,” “because,” or “but.” Each finite clause linked by kuma still needs the subject–TAM marking licensed by that clause.
For the complete phrase-level system, see da for Noun-Phrase Coordination. Event chains without an overt linker are developed on Coordination without an Overt And.
First count grammatical slots, not English ands
- Are X and Y jointly the subject, object, or complement of one predicate? Use X da Y.
- Does each part make its own claim with a finite predicate? Use kuma, another meaningful linker, or well-formed juxtaposition.
- Does postverbal da introduce a person involved in the event? Check whether that person is a second object or merely a companion.
- Is the intended relation sequence, cause, condition, or contrast? Kuma may be too vague; choose sannan, saboda, idan, amma, or another accurate linker.
Amina da Kabiru sun gabatar da rahoton tare.
Amina and Kabiru presented the report together. (one coordinated subject)
Amina ta gabatar da rahoton, Kabiru kuma ya amsa tambayoyi.
Amina presented the report, and Kabiru answered questions. (two added propositions)
The first combines two people before one plural sun gabatar. The second gives each person a separate clause and a separate contribution.
Da builds one coordinated noun phrase
Inside a noun phrase, da is invariant for gender and number.
Na ɗauko takardu da alƙalami daga ofis.
I fetched documents and a pen from the office. (coordinated object)
Za mu tanadi shayi da ƙananan waina domin baƙi.
We will provide tea and small cakes for the guests. (coordinated object)
Malamai da iyaye sun tattauna matsalar halartar yara.
Teachers and parents discussed the problem of children’s attendance. (coordinated subject)
The complete phrase fills one slot. When X da Y is the subject, its combined reference is plural even if each conjunct is singular.
Binta da ƙanwarta suna duba hotunan bikin.
Binta and her younger sister are looking at the celebration photographs.
Kwamfuta da na’urar bugawa za su isa gobe.
The computer and printer will arrive tomorrow.
Plural suna and za su diagnose the coordinated subject. English speakers sometimes let the nearest singular noun influence agreement; Hausa agreement targets the whole combined set.
Pronouns after coordinating da are independent forms:
Ni da kai za mu sake lissafa kuɗin.
You and I will count the money again. (addressing one male)
Hauwa da ita sun raba aikin gida.
Hauwa and she divided the housework.
The plural subject markers are za mu and sun. Forms such as object ka or ta cannot simply replace independent kai or ita after coordinating da.
Kuma adds a proposition or an additive contrast
Kuma can stand near the boundary between clauses or after the newly contrasted subject. The second clause remains finite.
Mun wanke tankin, kuma mun sake cika shi da ruwa.
We washed the tank, and we filled it with water again. (same subject, added event)
Nura ya gyara kujerun, Sa’ida kuma ta share ɗakin.
Nura repaired the chairs, and Sa’ida swept the room. (different subjects)
Za mu kammala binciken yau, kuma za mu aika sakamakon gobe.
We will complete the investigation today, and we will send the result tomorrow. (two separately framed future assertions)
In Sa’ida kuma ta share, placing kuma after the second subject highlights Sa’ida’s additional or contrasting contribution. It does not replace feminine ta. With a continuing subject, kuma can occur after the marker:
Bello ya sayi magani. Ya kuma kai mahaifinsa asibiti.
Bello bought medicine. He also took his father to hospital.
This use is close to English also. The placement helps attach the addition to the predicate rather than build a new coordinated noun phrase.
Paired choices in one event setting
Suppose two technicians inspect equipment together:
Rabi da Sani sun duba famfon a safiya ɗaya.
Rabi and Sani inspected the pump on the same morning. (joint coordinated subject)
Rabi ta duba famfon, Sani kuma ya duba janareta.
Rabi inspected the pump, and Sani inspected the generator. (separate contributions)
The da version packages Rabi and Sani as one plural actor, though it does not by itself prove they performed every movement jointly. The kuma version preserves two propositions and can assign different objects.
The distinction also appears with objects versus clauses:
Mun sayi bulo da siminti a kasuwar gini.
We bought blocks and cement at the building-materials market. (two objects of one purchase predicate)
Mun sayi bulo, kuma muka yi odar siminti daga Kano.
We bought blocks, and we ordered cement from Kano. (two finite events)
In the second sentence, narrative/relative completive muka anchors the added event. Bare kuma yi odar would be incomplete.
Da after the verb may mean with
With subjects, position and agreement give a strong diagnostic:
Musa da Ladi sun je wurin taron.
Musa and Ladi went to the meeting place. (coordinated subject)
Musa ya je wurin taron da Ladi.
Musa went to the meeting place with Ladi. (Ladi is a companion)
The first has joint plural sun. The second has masculine singular ya, so Musa is the grammatical subject and da Ladi is comitative. Add tare da when accompaniment needs to be unmistakable:
Musa ya je wurin taron tare da Ladi bayan aiki.
Musa went to the meeting place together with Ladi after work.
Postverbal object strings can be less decisive:
Likitar ta duba uwar da jaririn a ɗakin jinya.
The doctor examined the mother and the baby / examined the mother with the baby present. (potentially ambiguous)
Likitar ta duba uwar da jaririn ɗaya bayan ɗaya.
The doctor examined the mother and the baby one after the other. (coordination clarified)
Likitar ta duba uwar tare da jaririn a gefenta.
The doctor examined the mother with the baby beside her. (accompaniment clarified)
There is no honest universal rule that makes the unexpanded first sentence have only one reading. World knowledge, discourse, and clarifiers resolve it.
Kuma does not specify every discourse relation
Kuma asserts addition. If the relation is more specific, use the connector that says so.
Mun gama lissafin, sannan muka kulle ofishin.
We finished the accounts, and then we locked the office. (explicit sequence)
Mun kulle ofishin saboda wutar lantarki ta ɗauke.
We locked the office because the electricity went off. (cause)
Mun kira direban, amma bai ɗauki waya ba.
We called the driver, but he did not answer the phone. (contrast)
Replacing sannan, saboda, amma with kuma would merely add claims and would hide sequence, cause, or violated expectation. Conversely, when no stronger relation is intended, kuma avoids overcommitting.
Aisha tana koyar da lissafi, kuma tana kula da ɗakin karatu.
Aisha teaches mathematics, and she also looks after the library. (simple addition)
A diagnostic transformation
Begin with Hauwa da Bala sun kawo abinci. Split the coordinated subject into two independently informative clauses:
Hauwa da Bala sun kawo abinci domin taron.
Hauwa and Bala brought food for the meeting. (one plural subject)
Hauwa ta kawo tuwo, Bala kuma ya kawo miya domin taron.
Hauwa brought tuwo, and Bala brought soup for the meeting. (two clauses)
The transformation requires more than replacing da with kuma. It also requires singular ta/ya, a predicate in each clause, and any distinct object. That is the clearest proof that the two connectors occupy different structural layers.
Mini-dialogue: together or separate contributions?
A: Waɗanne mutane suka shirya liyafar? B: Maryam da Usman ne suka shirya ta.
A: Which people organized the reception? B: Maryam and Usman organized it. (coordinated focused subject)
A: Wane aiki kowannensu ya yi? B: Maryam ta shirya wurin zama, Usman kuma ya kula da abinci.
A: What did each person do? B: Maryam arranged the seating, and Usman took care of the food. (separate contributions)
Using Maryam da Usman in the second answer would group the people but would not align each one with a distinct task. Using two kuma-linked clauses in the first would answer with contributions rather than simply identify the joint organizers.
Common Mistakes
1. Using da between two finite clauses
❌ Hafsa ta buɗe shagon da Kabiru ya kunna fitilu.
Incorrect mechanical translation of clause-level and.
✅ Hafsa ta buɗe shagon, Kabiru kuma ya kunna fitilu.
Hafsa opened the shop, and Kabiru switched on the lights.
2. Giving a coordinated subject singular agreement
❌ Babana da kawuna ya dawo daga tafiya.
Incorrect—two coordinated people require plural agreement.
✅ Babana da kawuna sun dawo daga tafiya.
My father and my uncle returned from the journey.
3. Letting kuma replace the second clause’s TAM marker
❌ Zainab ta wanke kwanukan, Ado kuma share teburi.
Incorrect—the second finite predicate lacks masculine ya.
✅ Zainab ta wanke kwanukan, Ado kuma ya share teburi.
Zainab washed the dishes, and Ado wiped the table.
4. Misreading accompaniment as a coordinated subject
❌ Salisu ya tafi banki da manajan.
Wrong for the intended equal co-subject meaning; the grammar presents Salisu as subject and the manager as companion.
✅ Salisu da manajan sun tafi banki.
Salisu and the manager went to the bank.
5. Using kuma for an intended causal relation
❌ Mun dakatar da aikin, kuma ruwan sama yana ƙaruwa.
Grammatical as two added observations, but it does not express the intended reason.
✅ Mun dakatar da aikin saboda ruwan sama yana ƙaruwa.
We stopped the work because the rain was getting heavier.
Key Takeaways
- Da coordinates noun phrases that jointly fill one subject, object, or complement slot.
- A coordinated subject takes plural agreement: sun, suna, za su, and related forms.
- Kuma adds a proposition or another participant’s contribution; every finite clause keeps subject–TAM marking.
- X da Y sun... coordinates subjects, while X ya/ta... da Y normally presents Y as a companion.
- Postverbal object + da + noun can be genuinely ambiguous between coordination and accompaniment; clarify with context, ɗaya bayan ɗaya, or tare da.
- Kuma is additive, not an automatic marker of sequence, cause, condition, or contrast.
